In order to meet a wide variety of social policy objectives (such as health, educational attainment, community cohesion and social inclusion), ensuring wide access to community and youth sport programmes remains an objective of many governments, particularly in areas affected by social inequality and reduced opportunities for participation. In the UK, the post 2012 Olympic Legacy Strategy, overseen by Active Partnerships under the auspices of Sport England, promoted Sportivate and Satellite Clubs programmes (aimed at increasing participation levels and improving long-term engagement in physical activity) through most of the rest of the decade, with a focus on strengthening pathways into sustained community sport involvement. In order to ensure minimum standards of operation, enhance safeguarding practices, and to develop the skills of the local coaching workforce, Active Sussex (one of the Active Partnerships) commenced a Coach Support Officer (CSO) scheme with the support of the University of Chichester from 2013 to (through various iterations) time of writing. Through a longitudinal reflection/summary of the various interventions and data collection points over the last nine years, the chapter presents an overview of this scheme. Further, the chapter outlines a clear philosophy, guidelines, and accompanying set of values that extol what can be considered good (best) practice for sustainable, inclusive, and community-centred sport and physical activity programmes. This was with particular emphasis on coach education, participant retention, safeguarding standards, and the long-term development of inclusive local sporting networks. alongside the role of reflective practice and encouraging intrapersonal agency for coaches to recognise how to establish and sustain programme effectiveness through coaching methods
